It is one of those quietly dangerous winter habits most of us never think about. You hop in the car on a frosty Aussie morning, turn the key, and drive off. But on cold nights and mornings, the warm engine bay you have just left behind is exactly the cosy hideaway a cold cat is looking for – and starting the engine while one is tucked inside can be fatal.
With stray and community cat numbers high across much of the country, Melbourne’s Lort Smith Animal Hospital has urged drivers to take just a few seconds to check their car before setting off this winter. It is a small habit that can genuinely save a life.
Why cats crawl into car engines when it’s cold
Cats run a higher baseline body temperature than we do, and in winter they actively seek out residual heat. A car that was driven an hour or two ago is still warm under the bonnet, dark, and enclosed – everything a cat wants when it is trying to conserve energy and stay out of the wind and rain.
It is not only strays, either. Indoor-outdoor pets and neighbourhood cats will happily climb up through the wheel arch and settle on top of a warm tyre or near the engine block. Kittens can squeeze through surprisingly small gaps, and mother cats have been known to move whole litters into an engine bay because it feels like a safe, elevated den.
The three-second check that can save a cat’s life
You do not need any special gear – just a quick routine before you start the car, especially on cold mornings or after the vehicle has been parked overnight. Rescue groups and vets recommend the following:
- Knock firmly on the bonnet. A few solid slaps usually startle a hidden cat enough to make it move.
- Give the horn a quick beep. A short toot before you turn the key is often all it takes to send a sleeping cat bolting.
- Have a quick look. Glance under the car, around the tyres and into the wheel arches before you get in.
- Listen for a moment. Meowing or scratching from under the bonnet is your cue to stop and investigate.
What to do if you find a cat in the engine
If you hear or see a cat once the car is running, switch the engine off straight away – do not try to drive to “shake it loose”. Open the bonnet and give the cat space and time to climb out on its own. A calm voice and some strong-smelling food, such as a little tinned tuna, can help coax a nervous cat into the open. If you need to handle it, thick gloves are wise, as a frightened cat may scratch or bite.
If the cat is wedged in, injured, or won’t budge, don’t force it. Call a vet, your local council ranger, or an animal rescue group for help. In emergencies where an animal is trapped, your local fire and rescue service may also assist. Cats have survived long journeys stuck in engine bays, so it is always worth stopping to check rather than assuming the worst.
Helping the strays in your street
If car engines are becoming a regular shelter for cats in your area, it is usually a sign there are community or stray cats nearby who are doing it tough over winter. A simple, dry shelter – even a weather-proof box with a warm blanket in a quiet corner – can give them somewhere safer to go. If you can, speak with your local council or a registered rescue group about desexing and rehoming programs, which are the most effective long-term way to reduce the number of cats living rough.
For your own cat, the safest option in an Australian winter is to keep them indoors overnight with a warm bed away from the garage. It protects them from the cold, from cars, and from the local wildlife – a win all round. If you are ever unsure about your pet’s health or behaviour, consult a licensed veterinarian for advice specific to your animal.
Frequently asked questions
Why do cats hide in car engines in winter?
A recently driven car stays warm under the bonnet for hours. The engine bay is dark, sheltered and enclosed, which makes it an appealing spot for cats trying to escape cold, wind and rain while conserving body heat.
How do I check my car for a cat before driving?
Before starting the engine, knock firmly on the bonnet, give the horn a quick beep, and take a quick look under the car and around the tyres and wheel arches. The noise is usually enough to make a hidden cat run off.
What should I do if a cat is stuck in my engine?
Turn the engine off immediately, open the bonnet, and let the cat climb out on its own. Tempt it with strong-smelling food and speak calmly. If it is injured or trapped, call a vet, council ranger, or animal rescue service rather than trying to force it out.
Is this only a problem for stray cats?
No. While strays and community cats are most at risk, pet cats and neighbourhood cats also climb into warm engine bays. Keeping your own cat indoors overnight in winter is the safest way to prevent it.
